python新类似乎违背了广度优先的执行顺序, 对象自定义计数实例化的多少

class TSSS():
    def f1(self):
        print('from TSSS')


class SSS(TSSS):
    def f1(self):
        print('from SSS')

class SS():
    def f1(self):
        print('from SS')

class S(SSS):
    # def f1(self):
    #     print('from S')
    pass

class A(S):
    def f1(self):
        print('from A')
        super().f1()

class B(SS):
# class B:
    def f1(self):
        print('from B')

class C(A,B):
    def f1(self):
        print('from C')
        super().f1()
    pass
print(C.mro())
c = C()
c.f1()

print(C.mro())

输出:

[<class '__main__.C'>, <class '__main__.A'>, <class '__main__.S'>, <class '__main__.SSS'>, <class '__main__.TSSS'>, <class '__main__.B'>, <class '__main__.SS'>, <class 'object'>]
from C
from A
from SSS
[<class '__main__.C'>, <class '__main__.A'>, <class '__main__.S'>, <class '__main__.SSS'>, <class '__main__.TSSS'>, <class '__main__.B'>, <class '__main__.SS'>, <class 'object'>]

第二种情景

class TSSS():
    def f1(self):
        print('from TSSS')


class SSS(TSSS):
    def f1(self):
        print('from SSS')

class SS(TSSS):
    def f1(self):
        print('from SS')

class S(SSS):
    # def f1(self):
    #     print('from S')
    pass

class A(S):
    def f1(self):
        print('from A')
        super().f1()

class B(SS):
# class B:
    def f1(self):
        print('from B')

class C(A,B):
    def f1(self):
        print('from C')
        super().f1()
    pass
print(C.mro())
c = C()
c.f1()

print(C.mro())

输出:

[<class '__main__.C'>, <class '__main__.A'>, <class '__main__.S'>, <class '__main__.SSS'>, <class '__main__.B'>, <class '__main__.SS'>, <class '__main__.TSSS'>, <class 'object'>]
